I’ve been using this app since the start of my business over 8 years ago. I wanted something fast, simple, and professional. I’m able to know if my customers saw my estimates or invoice which is great. lol

Support

No support. The tech team will suspend your ability to message if you give them a tricky question. This app stinks it will hurt your business as it did mine! Help me!

★★★★★Sep 29, 2026
Helps me out a ton!

Easy to work with. My clients love it because it’s so user friendly.

★★★★★Sep 23, 2026
Not working!

Very disappointed with this app. I’m paying a monthly subscription fee, but the app isn’t working properly and I can’t use the service I’m paying for. If you’re going to charge customers a subscription fee, the app should actually work. I hope the company fixes this issue and provides a refund or credit for the time the service has been unusable.

★★★★★Sep 21, 2026
Bugs

App is awesome and fat, but it’s getting to be too expensive to deal with the same bugs 1. Doesn’t log you out 2. Doesn’t sync well to web 3. Fail delivery on text and email 4. Constant loading symbol on screen Getting old.
